V. Additions to the Fossil Fauna of Antigua. 



Two small but valuable collections from Antigua have recently 

 been sent to me for examination. One consists of some mollusca 

 and corals from the ' upper limestones ' (of Purves) ; it has been 

 forwarded by Mr. Jukes-Browne. The mollusca belong to the 

 genera Melanopsis and Turritella. Mr. Edgar Smith has kindly 

 examined these with great care, but is unable to identify them with 

 any recent species. The best-preserved coral is a specimen of 

 Prionastrcea diversiformis (Mich.), a typical species of the Italian 

 Miocene (Helvetian). It has been previously recorded from Antigua 

 by M. Purves. 3 



I cannot name the other corals without more material for com- 

 parison from the Miocene of Piedmont. 



The second collection was sent by J. Vincent Forrest, Esq., M.B. 

 It is of much interest, as it contains two of the echinoids which 

 are most typical of the West Indian Oligocene. They are Echinan- 

 ihus (or Diplothecanihus of Duncan) concavus (Cott.) 4 and E. Antil- 

 larum (Cott.). 5 No echinoids had been previously recorded from 

 the island. These are of great value, as establishing the correlation 

 of the beds in which they occur with those of St. Bartholomew and 

 Anguilla. 



The coral described by Duncan as Alveopora dcedalea is also 



1 Haeckel (Zool. 'Chall.' Exped. vol. xviii. pt. 1, 1887; Radiolaria, vol. i. 

 p. 432) has renamed this species tripodiscus ; as the reason for the change is 

 not apparent, I retain the earlier one. 



2 Haeckel, op. tit. p. 1070, has renamed this species Ehrenbergii.
